Question

please help me in deriving heron's formula

Answer 1

first step - you have to find the perimeter and divide it by 2 so u will get semi perimeter (that will be S)

second step - then u have to find all the sides ( sometimes only 2 sides r given )

third step - then u have to write ​s (s-a)(s-b)(s-c)with whole upon under root

a , b , c are the first , second , third sides respectively ....

Answer 2

1

Consider a right triangle ABC, right angled at vertex C, with sides as a, b and c where a and b are legs and c is the hypotenuse.

2

Our goal is to prove a2 + b2 = c2

3

The area can be written in two ways

Using Heron's Formula Area = square root of s(s-a)(s-b)(s-c), where s is the semi-perimeter of the triangle given by (a + b + c) / 2
